What are disadvantage and advantages of connectionless?

Connectionless communication offers advantages such as reduced overhead and faster transmission since there’s no need to establish a connection before data transfer. This makes it suitable for applications like streaming or gaming, where speed is crucial. However, disadvantages include a lack of reliability and error-checking, as packets can be lost or arrive out of order without a guaranteed delivery mechanism. Additionally, it may lead to increased complexity in application-level protocols to handle these issues.
